Thanks to all. My original calculations were correct. Just worried there was some lurking structual steel loading case that I was not aware of.

I have attached a sketch of the proposed stringers and angle tread plate supports. http://files.engineering.com/getfile.aspx?folder=8769c065-deae-4ecb-88a2-e4b689cd20dc&file=stairs.pdfhttp://files.engineering.com/getfile.aspx?folder=8769c065-deae-4ecb-88a2-e4b689cd20dc&file=stairs.pdf

Ok - the above is incorrect. The value listed in the ASD chart under the P/omega header is the allowable max value. The more I look at this isn't the angle(s) in flexure not tension?

Thanks for the reply. To make sure I have this correct. For yielding, I divide the Normal Load applied to single angle by omegaa (1.67). If the quotation is less than the value publish in Table 5-2 of the AISC Handbook I am good. Plus some factor of safety,

I am building a loft in my shop, and I need help analyzing the stairway. I am going to make the stringers from steel channels then weld angle iron the the channel to support the tread plates. Do to space constraints, I do not want to attach the tread plates to the angle iron supports. The...

Is it possible to simulate a punch and die in Algor MES package?

Thanks for the reply. I am just concerned with the compressive stress in the dowel pin alone right now. We are using 12723lbf (1800psi on a 3" bore cylinder) to insert the pin. The pin never fails but if you look at the stress it would suggest that it just "blow" apart. It is a standard heat...

We are inserting a dowel pin thru a hole into a plate. The pin to the hole has an interference fit. We have noticed that at times the pin will split the plate during insertion. While trying to model the assembly to redesign the plate I have come across something that I can explain. If you look...

I have been charged to produce a standardized template for the procurement of Capital Equipment. Does any have a general template they would be willing to share?

Ok, we have the plates and beams working together now. The next question is, have we modeled this correctly? To simulate the nailing of the sheeting to the 2 x 4, we have spaced the nodes on the beams and plates to match the spacing in production. Results seem to correlate the model to our...

Thanks Garland. It appears that I am heading in the correct direction. I was using your #2 solution. What about the results - does the plate have an affect the stress indicated in the beam results. It current does not, but it is probably due to not enough nodes aligned to transfer load.

Is there a way to align the nodes of the beam to the plate? Will the reported beam stresses and displacement be with or without the plate?

Um, maybe everything is ok. I did look under the the beam results menu. Is there anyway to see the result of both together. We are interested in the rotational displacement and stress value.

I have a beam model now I need to add a plate. Picture a house. The beams are the 2 x 4 and the plate is the sheeting. When I add a part and define the elements as plates, apply the beam offset, solve, only the plate is solved. What I am missing?

I figured it out. I was entering a diameter when it was asking for a radius.

I have imported a wireframe model into Algor V16 using superdraw and then exported to Fempro. Everthing looks ok, apply my beam definitions then check the weight and I am about 3x more than my solid model. Units check out ok. Measured several beams in Algor and they match the math model. Has...

We have an older version of Algor. V16 with MES. We know the mass, velocity and the desired deaccelation of the projectile. Is it possible to simulate an impact?

Should be "I got it to work" How do you edit posts?

All got it to work!!!!

I found the divid by lines command. Thank you again, GBor.
